Noise Prediction and Control in offshore Structures

The concept of crew habitability in relation to drilling vessels has reached greater significance in recent years reflecting tougher regulatory criteria, and a greater appreciation of the fatigue-inducing effect and long-term health issues associated with protracted exposure to high levels of noise and vibration.  Hence, shipbuilders are looking to limit noise and vibration on ship as much as possible, particularly on accommodation quarters on the drilling platform. Ideally, potential problems should be identified at the earliest stages of drilling platform design and building, as well as in the initial stages of parts design and manufacture. However, it is challenging to predict using today’s acoustics computer modelling software. This project aims to develop a new practical and theoretical program for accurate narrow-band width prediction of the noise and vibration control.
